文摘

Areas contributing baseflow to streams can in principle be delineated using wellhead protection methodology. This is a protection strategy to maintain the quantity and quality of groundwater discharge to sensitive streams. The delineation can be affected by the choice of groundwater model and the capture zone delineation method. The Pollock method for particle tracking should be chosen over the 4th Order Runge-Kutta method for heterogeneous systems. Capture zone delineation by particle tracking should be combined with reverse transport to address parameter uncertainty.
